Title: Improvements in or relating to apparatus for the stimulated emission of radiation
Inventor: SILFVAST WILLIAM THOMAS
IPC: H01S3/227
Filed: 1969-09-15
Abstract: 1,255,983. Lasers. WESTERN ELECTRIC CO. Inc. 15 Sept., 1969 [16 Sept., 1968; 28 April, 1969], No. 45280/69. Heading H1C. Ultra-violet or visible radiation is produced by an active medium comprising atoms of helium and/or neon pumped to their metastable state and a vapour of an element selected from zinc, magnesium, aluminium, gallium, indium, thallium, beryllium, germanium, cadmium, tin or lead. With a given element (#) and an upper energy level (*), the reactions in the medium are or A suitable laser assembly is shown in Fig. 1 in which a quartz tube terminated by Brewster windows 13, 14 is formed with reservoirs 18A- 18E accommodating a solid element such as a selected isotope of cadmium. The reservoir is maintained by a temperature control apparatus 20 at a temperature such as 230 to 300 C. sufficiently low to maintain the element in the solid or molten state, while the tube is heated to a controlled temperature of about 50 C. higher by an oven 19 or a heating coil wound about the tube to provide sufficient vapour pressure of the element. The inert gas is pumped to a metastable state by a discharge current from a source 17 between electrodes 16, and the laser output is produced by radiative ionization of the vaporized element as a result of non-radiative energy transfer from the excited inert gas. The arrangement may operate as an amplifier if the resonator dichroic mirrors 21, 22 are omitted. In a modification, Fig. 3, the possiblity of vapour deposition on the tube windows is minimized by the use of two discharge anodes 15A, 15B and a common cathode 16.

The melt should have a sulphur content of 1 to 25% b.w. and preferably includes other salts, e.g. alkali metal carbonates, and a catalyst, e.g. iron in amounts of from 6À5 to 7% b.w. of the melt. The carbonaceous material may be natural gas, coke, coal, fuel oils, petroleum residues, lignite, peat, wood, municipal waste, sewage sludge, industrial waste, e.g. P.V.C., rubber, plastics, and agricultural wastes. Preferred temperatures in both zones range from 800‹ to 1200‹ C. Melt may be withdrawn at 122 for the removal of impurities and recycling at 116.

IPC: C07D503/00
Filed: 1974-10-22
Abstract: Compounds of formula III <IMAGE> wherein COR<2> is an acyl radical of a carboxylic acid and R<8> is hydrogen, an organic radical or a cation of a pharmaceutically tolerated salt are prepared by reacting a carboxylic acid of formula R<2>-CO2-H     (V> or its reactive functional acylating derivative with a compound corresponding to formula III but containing a hydrogen atom instead of COR<2>. Uses of the process according to the invention are directed to the removal of a radical R<8> cleavable by hydrogenation, and to the hydrogenation of the group -CH2OC-OR<2> to give a CH3 group. The compounds prepared find pharmacological applications since they inhibit  beta -lactamase. They are also suitable for use as intermediates for the preparation of other pharmacologically useful substances.

Title: Method of and apparatus for enciphering and deciphering message signals
IPC: H04L9/00
Filed: 1965-11-05
Abstract: 1,122,639. Pulse signalling. CIBA Ltd. 5 Nov., 1965 [6 Nov., 1964], No. 47059/65. Heading H4L. Apparatus for coding signal pulse sequences to ensure secrecy comprises means for mixing each signal pulse of a sequence with a different pulse in a pseudo-random pulse sequence to provide at the output combined pulses on the occurrence of one binary value in an auxiliary binary code pulse sequence, and means acting on the occurrence of the other binary value of the auxiliary pulse sequence for adding a predetermined pulse amplitude value to said combined pulses when the amplitude value of the latter does not exceed a predetermined threshold value and for subtracting said predetermined amplitude value when the amplitude value of said combined pulses does exceed said threshold value. In a circuit for coding quantized amplitude modulated pulses, Fig. 9, the signal pulses K, and pulses S whose amplitudes vary discretely in a pseudo-random manner, are added at 22 and supplied via an OR gate 35 and AND gate 39 to the output C. The combined pulses are also supplied to a threshold detector 24, supplying an AND gate 28, and via an inverter 25, to an AND gate 29. Gates 28, 29 and 35 are controlled by the auxiliary pulse sequence S<SP>*</SP>. It it assumed that amplitude values in the pulse sequences K and S differ by steps of 0.1 volt and that the amplitude values in each case may extend from 0 to - 1À5 volt. Thus the combined pulse sequence may have values extending from 0 to- 3À0 volts. The auxiliary binary coded pulse sequence S<SP>*</SP> has the two values-6 volts or 0 volt representing 0 and 1 respectively. When the value 0 occurs in the pulse sequence S*  the gate 35 passes to the output the more positive of its two inputs, i.e. the combined pulse output from 22. Gates 28, 29 are blocked and provide a signal blocking a subtraction circuit 33 and an addition circuit 34 so that 0 volts appears on lines 37, 38. Since gate 39 passes only the most negative potential at its inputs, the output of 22 passes to the output C unchanged. The occurrence of binary 1 in the sequence S<SP>*</SP> causes gate 35 to transmit the value O volt to the output gate 39. The threshold detector 24 provides an output potential of 0 volts as long as the amplitude value of the combined pulse sequence is less than 1.6 volt and of - 6 volts when the amplitude value is equal to or greater than 1.6 volt. Thus a signal will be passed by gate 32 when the output of threshold detector 24 is 0 volt and by gate 29 when the output is - 6 volts. Gates 31, 32 control circuits 33, 34 respectively, circuit 33 causing 1.6 volt to be subtracted from the combined pulse sequence appearing at the output of circuit 22 and circuit 34 causing 1.6 volt to be added. The decoding circuit, Fig. 10 (not shown), operates on similar lines. The input signal and pseudorandom pulse sequences may be in binary coded form, Figs. 11, 12 (not shown), and the required addition and subtraction obtained through counting chains.

Title: Condition Monitoring System
IPC: G08B23/00
Filed: 1966-10-21
Abstract: 1,169,031. Alarm systems. JOHNSON SERVICE CO. 21 Oct., 1966 [22 Oct., 1965], No. 47346/66. Heading G4N. An alarm system comprises a number first (visual) indicators 6 each having three states and each indicating the state of a condition at a related point, and a common second (accoustic) indicator 11 also having three states. Actuation of a condition sensing switch 19 causes its associated lamp 6 to flash intermittently and the horn 11 to sound intermittently. Actuation of acknowledge switch 15 turns off horn 11 and energizes lamp 6 steadily. When sensing switch 6 restores to normal lamp 6 is extinguished, and horn 11 is continuously energized until switch 15 is again actuated. As shown, contacts 19 may be operated by a temperaturesensitiva bi-metal strip or by humidity-orpressure-sensitive means and become closed in response to an abnormal condition. On closure, contacts 19 complete the output ciruit of transistor 22 via diodes 20, 34 so that warning lamp 6 is flashed over periods of 1À2 seconds under control of a free-running multivibrator 24. The emitter circuit of transistor 22 is coupled to the base of transistor 35 so that horn 11 is sounded during the period when the lamp 6 is extinguished. This warning acknowledged by manual closure of contacts 15 which turn on silicon controlled rectifier (SCR) 41, allowing the lamp 6 to operate continuously via diode 45. This action reverse biases diode 20, turning off transistor 22 and turns on transistor 48, inhibiting operation of the horn-controlling transistor 35. When the fault or abnormal condition has been cleared, contacts 19 open, turning off transistor 48 so that transistor 35 becomes turned oh via diodes 54, 55, giving a continuous sounding of the horn 11. When this faultterminating signal is acknowledged by manual closure of contacts 15, SCR 57 is turned on, turning off the horn-controlling transistor 35. A test button 18 is included for lamp 6. Further condition-sensing circuits and indicating lamps may be connected to the conductors at the upper side of the figure.

A combined starting relay and thermal cut out for an electric motor has a thermal switch mounted within an insulating casing and the coil 28 of the relay mounted externally on the casing.
